Dont be fooled by the powder coated cheap knock offs, they do not work!

The most essential tool for building an AR15. This tool works with delta ring/star barrel nuts and also most free float barrel nuts. Will also assist with tightening the castle nut on a buffer tube. whatever task you throw at this armored wrench, it will get it done. Weighing in at 1lb 6oz, it is also great for attitude correction.
